2004 Volkswagen Passat TDI Problems

Check Engine Light Due to Issues With Glow Plugs/Wiring Harness

Because of issues with the glow plugs and/or the glow plug wiring harness from the control relay, the Check Engine Light may illuminate. Our technicians tell us there is a service bulletin, not a recall from Volkswagen regarding replacement of the glow plugs on 2004-2005 model years only.

    Camshaft Wears Down Prematurely

    The 2.0L TDI engine used in the Volkswagen Passat TDI very commonly faces camshaft lobe wear issues causing:

    -Pronounced loss of power

    -Backfire through the intake (heard under the hood)

    -Rough vibrations while the engine is running

    -decreased fuel economy

    - OBD trouble code P0101

    Correction for this issue requires substantial internal engine work including replacement of the camshaft, hydraulic lifters, and possibly fuel injectors

    To help avoid this issue, ensure you are using the correct oil for your engine, as listed in your owners manual. 

    Engine Oil Leaks

    Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.
